Hi,
I am not really an expert, but I think the "Local link" may use Loop back,
instead of actually testing the Network / IPv6 stack.
I have requested my network guru (james) to look at it. We are going to try
with new OS also and will update. Here is some info for clarity...
James says...
Link-local is the fe80 addresses that refer to devices on a particular data
link, such as a single Ethernet network, or a point-to-point serial connection.
If you're using your own link-local address, then yes, that traffic will - I
believe - traverse the loopback interface.
I've downloaded the beta version of Ubuntu 9 but haven't yet installed it.
I've also got the most recent kernel source but keep running out of space
trying to get it built and installed.
=======
Yes, I have tried earlier with locallink. It works fine.
here is my network info.

Following is the IPv6 address of the next node.
I have taken different snapshots for the IPv6 failure to get some good idea.
